Abstract

The presently disclosed technology is directed toward the removal of plugs in a pipeline segment by installing one or more clamping devices onto a pipeline. The clamping device will have the ability to access the inside of the pipeline segment and inject media designed to dissolve the plug.

Claims (36)

1. A method for remediating a pipeline segment comprising:

clamping a first remediation device to a pipeline segment;

drilling a perpendicular hole into the pipeline segment;

injecting a media into the pipeline segment;

clamping a second remediation device to a pipeline;

clamping a third remediation device to a pipeline;

removing media from the pipeline via the second remediation device;

removing media from the pipeline via the second remediation device; and reintroducing the media to a second pipeline segment via the third remediation device.

2. The method of claim 1 further comprising identifying a pipeline segment with an internal obstruction.

3. The method of claim 1 further comprising removing an obstruction in the pipeline segment.

4. The method of claim 1 further comprising installing a means for plugging the previously drilled hole.

5. A method for remediating a pipeline segment comprising:

clamping a first remediation device to a pipeline segment;

drilling a perpendicular hole into the pipeline segment; and

injecting a media into the pipeline segment, wherein the media is a gel.

6. The method of claim 5 further comprising removing media from the pipeline segment.

7. The method of claim 5 further comprising clamping a second remediation device to a pipeline.

8. The method of claim 7 further comprising clamping a third remediation device to a pipeline.

9. The method of claim 7 further comprising removing media from the pipeline via the second remediation device.

10. The method of claim 5 further comprising identifying a pipeline segment with an internal obstruction.

11. The method of claim 5 further comprising removing an obstruction in the pipeline segment.

12. The method of claim 5 further comprising installing a means for plugging the previously drilled hole.

13. A method for remediating a pipeline segment comprising:

attaching one or more means for introducing media onto a pipeline segment using a means for attaching to a pipeline;

drilling one or more perpendicular holes into a pipeline segment using a drilling means;

introducing media means for removing a pipeline obstruction into the pipeline segment;

removing the pipeline obstruction from the pipeline segment using a plurality of means for removing media from a pipeline segment; and

linking the means for introducing media together to transfer media from a first pipeline segment to a second pipeline segment.

14. The method of claim 13 further comprising removing media from the pipeline segment.

15. The method of claim 13 further comprising clamping a first remediation device to a pipeline.

16. The method of claim 15 further comprising clamping a second remediation device to a pipeline.

17. The method of claim 16 further comprising clamping a third remediation device to a pipeline.

18. The method of claim 16 further comprising removing media from the pipeline via the second remediation device.

19. The method of claim 13 further comprising identifying a pipeline segment with an internal obstruction.

20. The method of claim 13 further comprising installing a means for plugging the previously drilled hole.

21. The method of claim 13 wherein the means for attaching to a pipeline is a means for clamping onto the exterior of an insulated pipeline segment.
